MSYS updated, again.
It appears that gremlins got into the packaging and the recent MSYS update was not, in fact, the Vista64 compatible release. I’ve now uploaded the correct archive and it should be available through the updater as we speak.
I’d also like to thank James Wilding for his invaluable assistance in ensuring the (right) msys archive was Vista64 compatible.
At the time of my posting this your link is currently pointing to “msys-1.0.10.exe 2005-06-27″ at sourceforge. Not sure how to construct a direct link to that one file, but the release_id should be in the neighborhood of 548678 instead.
Thanks Cory, fixed now
